Product and Software: This article applies to Aruba OS 3.1 and later.
AP allows 64 associations by default, which is configurable. If the current number of associations reaches the maximum number of allowed associations, the message "AP is resource constrained" are displayed in the output of the "show ap debug mgm-frames" command.

From above it can be seen that client is trying to associate but AP does not allow association as it has reached maximum number of allowed associations.
* Latest messages are logged on top in output of 'show ap debug mgmt-frames'.
To fix this problem, use the WebUI or CLI to configure the SSID profile for appropriate number of associations per AP.
Navigate to Configuration > select AP Group > Wireless LAN> Virtual AP> select Virtual AP> click SSID Profile> Advanced and change Max associations.
